Til/01y 00771067711. that I, HERBERT WILFRED I the King of England, and a resident 'of Trichinopoly, India, have invented certain new and useful Improvements Renewable Caps forPermanent Way-Bails, of which the following is a specification.

This invention has reference to permanent way-rails, and more articularly to such rails as are provided wit a renewable wearing- To ail whom it Be it known PERRY, a subject of 1 than the depth of the sides wardlyeinclined sides slightly f the head of the rail, so that when the cap is put onto the rail the lower edges of its sides necessarily extend downward be 0nd the sides of the headof the rail. This a lows of the projecting lower edges of the sides of the cap after the cap is laced on the rail. being hammered or bent in under the sides of the head of the rail, so as to fit closely to it and prevent the cap rising or longer in depth d surface or capping. being lifted off the rail again.

In British Patent No. 4,859 of 1900, grant- Drawings, showing in Figure I a section of en to myself, a ermanent way-rail is esuch a cap with one of its sides straight as scribed which I invented and which had a when put onto the .rail and the other side r 5 renewable wearing-surface or cap The sides after it has been hammered and bent in under of thiscap were made curved or bent inward, the head of the rail, accompany this specificaso as to fit closely. under the head of the rail; 1 tion. but this gave, an unrollable section to the cap Thus while this improved renewable cap is and necessitated its being slid onto or off the of a rollable section and can be put onto a rail rail from one end. In British Patent No. from above at any part of its length it also 21,169 of 190%, also granted to myself, aperhas the strong attachment to the rail of the manent way rail is described which I infirst cap, which was of unrollable section and vented and which had an improved. renewrequired to be slid onto the rail from one of its able cap. The sides of this cap weremade ends.

To strong as in the former rail,for it wasefiected limit these bent-in engths and to facilitate by the friction or grip obtained by making 1 their bending, little nicks or cuts may be cut the inner sides of the cap a little steeper or l across the projecting edges of the cap at the 5 more nearly vertical than those of the head ends of each of the lengths or portions which of the rail onto which it fitted, so that when it is desired to bend in under the head of the pressed down by the weight of the wheels of rail.
